-- DISCHARGE-GATE FOR STORAGE-RECEPTACLES.

Specification of Letters Patent. Patented J 31L 18 1921 lspliaasnmedmy i2, 1919. Serial No. 310,413.

T 0 all whom it may 0m Y Be it known that L FminnnioK N. l/Vrrrrn- SELL, a citizen of theUnited States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Discharge-Gates for Storage-Receptacles, of which the following is a specification. v j I I This inventionrelates to means for 010s ing the discharge chute from a storage receptacle during the timethat mater al, contained in said receptacle,' is fiowingtherefrom. a r g V The object of the inventionis to provide positive, powerful mechanismof this class which is especially adapted for stopping the flow of material contained in such receptacle, particularly .where v the material is composed of a great volume of large heavy objects of irregularshape, such for instance as chunks of coal flowing from a storage bin to a railroad car or locomotive or the like. a Y. 1 V

The invention consists in mechanism in carrying out theforegoing objects which can be easily and economically made, which is satisfactory and positive in operation and is not readily liable to get out of order, and

more particularly a in a gate mechanism adapted to cut through oracross a chute which is so positively and accurately controlled that it can be easily held many given position or moved atthewill of the operator in either direction v More particularly, the invention consists in featuresand details of construction which will be hereafter more fully set forth in the 4 specification and claims.

Referring to the drawings in wh ch sim1- indicate the same parts Figure 1 is a front view of a receptacle chute equipped with mechanism of this in vention in its preferred form.

. Fig.2 is aside 16\ of the device of F ig.

,1, enough of-theexterior parts of the chute being broken' away so to aiforda clear view of the operating mechanism. I: Fig. 3 is a-detail sectional plan viewtaken The devicefofthis inventionis shown plied to one side wall 10 ofa coal or other material receptacle from which projects a mainchute member 12 leading to suppleprises a bottom plate 16, two side walls 18, and a cover plate 20 hinged at the whole so arranged so as to form at the lower ex-. tremity of the device a discharge port closed by the semi-circular gate 24 leading tothe supplemental chute 14, suspended by arms 26, pivoted on trunnions 28, carried on sides 18 of the main chute by bracket members 31 (Fig. 3). Grate member 24is rigidly securedat its opposite sides to arms 30 journaled aboutsaid trunnions 28 more specifically the arms take direct bearing upon the tubular members 32, fitted over the trunnion bolts 28. These members 32 are provided to afford rigidity of.construction'when in operation and easy dismounting of the gate when it is necessary to remo'WitQE-ach arm 30 is rigidly secured by any suitable means, as

for instance, the rivets'36 to the web'of an rivets 48 through different selected groups of 11019952 provided for the purpose.

Each chain42 travels over and is driven by an independent wheel 54 on a shaft 56,

driven by a wheel 58, operated by any suitablefmeansas an ordinary p'ull chain 60.

There isone 'chaiiif42'on' each'side of the chute 12, each having its own sprocket wheel 54: on shaft 56 from which it will. be seen that adjustments of these chain devices may be made independently at points 44 and 46, heretofore described, through the'proper use of adjusting nuts 62 provided for. the purpose.- This has a distinct advantage over using direct intermeshing gearing at opposite sides of the chute.

Fig. 2 of the drawing shows the gate 24 in closed position. lVhen it is open the mechanism described is operated to rotate it in a counter clockwise direction about trunnion 28 through an opening 66 provided for the purpose between main chute 12 and supplemental chute 14. When the door has been moved completely through this opening 66 coal or other material in the main recep- I tacle can pass down chute 12 into the supplementalchute 14. When it is desired to stop the flow of such material, the operator manipulates wheel 58 to rotate wheels 38 and consequently gate 24 in a clockwise direction. As the gate so moves its upper edge passes to the leftithrough opening 66 and" cuts into and through the flowing material in chute 12 until the entire gate-reaches the position of Fig. 2 where .the flow of mate- .rial is entirely shut olt.
